PURPOSE:To enable reliable detection of four-wheel-drive state through single switch mechanism by improving two fork shaft mechanisms for two wheel and four wheel driving is power flow path. CONSTITUTION:When first fork shaft 40 is displaced to four-wheel-drive position D4 while a power distributor is brought to high speed power row four-wheel- drive state, a ball 17 is pushed up from second step section 42 to first step section 41 to pressure deform a pin 18. Consequently a ball 62 will press in a push rod 61 to bring a switch device 60 to ON state. Then second fork shaft 50 is displaced to neutral position thus to bring the power distributor to neutral, and the pin 18 is removed from between the balls 17, 62 to make the ball 62 movable to the left untill contacting against the face of second notch 52 thereby a push rod 61 will project to bring the switch device 60 into OFF state. |
